Need suggestions…

I’m starting an awards site…where people that are members of the community can come, recommend videos to be judge, once judge i can put them up for a vote through the website and have them voted on…

So i take it i need 3 plugins: Membership plugin, Submission plugin, and Voting plugin?

1. I don’t want it to be a paid membership right now…just a simple join, and i can confirm who are a part of this community and your in.
2. I want to be able to give everyone access to vote again every year, but only have 1 vote per year.

I’m new to wordpress and all the different plugins can be quite daunting….so thank you in advance for the suggestion of plugins!
